This has to do with the fleet add that Sv 39 was supposed to get
on the same day the previous round of BSEP deployments came out.
The fleet add wasn't on the timings I said they added, so it's in
between the permers.
Past 2 weeks 8205A has been doing Sv 39 on almost all the weekdays
I spotted, off-peak 8205A will be in front of 8216T. 8205A is still
on Sv 39 today as well. If 8205A was a SP, I would just think it's
replacing some random bus in workshop. But 8205A is perm BN 12, and
it's quite weird that it would be stuck on Sv 39 for weeks given
its perm status.
9456K on the other hand, has been stuck on Sv 12 for the same
period since 8205A appeared on Sv 39. On one of the days in the
past weeks, it did Sv 10 IIRC but the very next day it appeared on
Sv 12 again.
Sv 12's e-tt I can't tell though if they converted a WSD to ADD,
because the timetable revision recently seems to be for the H1
schedule, not the normal weekday schedule..
Just to add onto my previous post, 8205A is on Sv 39 again as
well today. (06 Dec).
To 'service_238', your previous post, did you mean 3131L
replaced 8205A on Sv 12? Or 3131L was a fleet add, just that 8205A
went out in the same period 3131L went in?
